Yes when you can no longer tighten the limb bolts down you have maxed out the limbs. Now keep in mind the max draw weight maybe off a bit from the specs of the bow. Several factors may cause this: slight differences in the limb manufacturing process, how you have your buss cables set up for the amount of let off,the number of twists on the cables, etc. My bow is supposed to max out at 70 lbs. I believe, I can only get about 63 lbs. last time I checked it. Some companies are better at getting their advertised specs out of their bows than others.
